Title: Phosphates
IPC: C01B25/455
Filed: 1970-11-27
Abstract: Complex phosphates of aluminum containing a halogen and chemically-bound molecule of a hydroxy compound, which may be water or an organic hydroxy compound. A typical example is a complex phosphate containing ethyl alcohol having the empirical formula AlPClH25C8O8. They are most conveniently prepared by the reaction of an aluminum halide with the appropriate hydroxy compound and orthophosphoric acid, under relatively cool conditions. The compounds are generally soluble in water and polar organic solvents. They decompose at low temperatures to give aluminum orthophosphate, thereby providing a method for producing aluminum phosphate in many forms, for example, fibers, coatings, binders and fine particles, from a solution in water or organic solvents.

Title: Nondestructive method for measuring states of surface and apparatus for carrying out said method
IPC: G01B11/30
Filed: 1971-01-05
Abstract: A beam of parallel rays which emerges from a perpendicular object-grid is reflected from a mirror surface and transmitted through a centered optical system to a Lummer dividing cube located at the image focal point of said system so as to produce a direct beam which is focused onto a photoelectric cell after passing through an image-grid and a beam which is deflected at right-angles and focused onto a second photoelectric cell. The image-grid is displaced transversely so as to stop light from the object-grid and the mirror surface is replaced by the surface to be studied. The quotient of the indications given by the two balanced photoelectric cells is characteristic of a given state of surface. The indication given by the deflected-beam cell provides the albedo of a given surface state and color.

Patent ES-454232-A1 (ES)
Title: Lens transducer for use in marine sonar doppler apparatus
IPC: G10K11/30
Filed: 1976-12-14
Abstract: An acoustic lens for marine doppler sonar apparatus of the type in which acoustic energy is radiated and received along a beam directed at an angle with respect to a ship's axis is fabricated so as to have an external surface substantially flush with the ship's hull and an internal surface angularly disposed with respect to the external surface. Electro-acoustic transformation elements are mounted on the internal surface. The lens material is selected to have an acoustic propagation velocity greater than that of water so that acoustic signals are refracted in passing across the lens-water interface. The lens prevents spurious acoustic signals that would ordinarily be reflected from the aerated water close to the ship's hull from reaching the electro-acoustic transformation elements.
Patent ES-454749-A1 (ES)
Title: Electronic security system
IPC: G08B13/24
Filed: 1976-12-31
Abstract: An electronic security system especially adapted for use in retail stores and employing a multi-frequency resonant tag circuit having distinct frequencies for detection and deactivation. A transmitting system provides an electromagnetic field within a controlled area at a frequency which is swept through a range including the detection frequency of the resonant circuit. In the presence of a tag circuit within the controlled area and operative at the detection frequency, pulses are detected by a receiver which includes noise rejection circuitry for discriminating true signals from noise. The receipt of a predetermined number of signal pulses within a prescribed interval of time causes an alarm actuation. The resonant circuit is formed by printed circuit techniques as a relatively small tag which can be affixed to an article of merchandise. The tag includes a fusible link integrally formed as part of the circuit and which can be fused upon application of an electromagnetic field of predetermined magnitude at the deactivation frequency of the resonant circuit. Deactivation of the tag destroys the resonant properties of the tag at the detection frequency such that a deactivated tag produces no alarm when passing through a controlled area.

Filed: 1977-01-26
Abstract: A tachometer (4) turns a transparent plate (5) instead of the usual indicator needle. The tachometer is fixed to a housing (1) held by reinforcements (3) to the vehicle. A shaft (7) able to rotate in respect of the housing carries two bearers (8, 9). The first bearer carries a light source (10) and the second bearer carries a photoelectric cell. The receiver and transmitter are arranged on opposite sides of the transparent plate. The photoelectric cell receives that part of light which is not absorbed by the transparent plate. The shaft (7) is mechanically connected by a pull wire (13) to the accelerator control. The transparent plate takes up a position dependent upon engine revolution speed and the light transmitter and receiver take up a position dependent upon accelerator control position. By imparting a predetermined transparency degree upon the plate, a signal can be obtained to give a regulated fuel air mixture.
